| Outline of Final Research Achievements |
We employed dual-energy CT (DECT) to measure the concentration of iodine in thyroid gland. In patients with Graves' disease, the correlation between iodine concentrations (ICs) measured by DECT and CT values were evaluated and then ICs were examined for the correlation to iodine uptake ratios (IURs) by thyroid scintigraphy. Moderate correlation was seen in the comparison with ICs and CT values. However, it was lower than the result expected from phantom study. IURs at 3h had moderate correlation to ICs. In conclusion, ICs measured by DECT may predict thyroid function in patients with hyperthyroidism.
